Lightroom: Allow facial recognition feature to re-index a folder/collection

  • (Edited)
Currently it is not possible to invoke a re-indexing of facial recognition data at either the global or folder/collection level. For my purposes re-indexing at the folder and collection level would be sufficient.

Reason: when a face is removed from a previously indexed image it is not possible to automatically recognize faces other than reviewing many images and manually applying a face region.

Please enable this, as the current functionality appears to be in a "beta" stage & is limited at the moment.

Yes, this is a function that should be available. Had tagging completed on a catalog with over 30k images in LR5 and upgraded. Went through tagging with facial recognition and was nearly done (5k left) and lost all tags but a few faces. Now, I've lost all person tags, even the ones I had in LR5.

With a large catalog 200K+ images as I have this is an essential. Additionally we need some control over the granularity over the face detection - at the moment FR is missing 30-40% of faces. We need to be able to say 'try again' and search harder!

Also re-indexing needs to be in two flavours - start from scratch on the selected images and secondly and more importantly search for faces not previously found - without removing those previously found and labelled.

Completely agree. The granularity is a feature offered in Picasa.

Completely agreed. Please include this in next update to Lightroom 6!

I see the inverse problem here occasionally (less than 1%) too: a face detection box that includes only a section of the background, or similar, which I have to manually delete. I've stared at several of these to try and see why Lightroom thinks there is a face there, and I just don't see it. It's like Lightroom is experiencing a strange computer version of pareidolia.

I fully agree. Lightroom needs two updates asap:
1) ability to rescan all photos for faces
2) ability to set granularity to the facial recognition function. There are currently approx 30-50% faces being missed in my photos. I am willing to manually deselect what is not a face rather than to have to go through all the photos to make sure there isnt a face missed

Additionally, I would welcome better selection management based on facial recognition. I currently cannot select 6 people and see only photo where they are all together.

Also, Lightroom found almost 30,000 faces in my photos. But it is terrible at grouping the faces together. I have many, many groups of my son in stacks of 4 or 5 photos, instead of 1 stack of hundreds of photos. Now that I have named a bunch of photos, perhaps reindexing would allow Lightroom to more intelligently create larger groups of photos of the same person?

Re-running face detection, globally and at the folder and selected photo(s) level, has to be a priority for the NEXT update. The "hit rate" for simply detecting faces in a photo (not identifying, just detecting that a face is there) is incredibly low. I'm seeing less than 50% success rate in detecting faces. Recognizing who is in each photo isn't performing well either, but failing to detect the only face in a portrait photo is a pretty big bug.

Two issues:
a) Reindexing photos - having LR clear and re-draw face regions on photos to allow people to fix mistakes (undelete, etc.)
b) Forcing LR to re-run matching logic on 1000s of faces that it guesses matches incorrectly. I've tagged 20K faces and some individuals have 100s of example faces tagged. I still have about 15K faces to go, but the match accuracy on these last images is poor (maybe 10%) instead of getting better. I want force LR to rerun the comparison logic of these labeled faces considering the faces already tagged. LR asking if my blonde niece is my dark haired son may have been acceptable at the start of the process, but I have 5K images tagged with my son, and 300 images tagged of my niece. Mismatches at this point is unacceptable.
b) Picasa offers an adjustable scale of the criteria to make a match. Such a tool could be helpful.

It would also be very nice if the facial recognition software was aware of context, because a lot of photos are already tagged with names, just not connected to the faces. If someone's name is in the keywords, chances are that the face is them, not someone that looks vaguely like them.

It would also be nice to restrict the face matching to certain groups, I'm not going to have a lot of my aikido friends show up in a photoshoot at a dance, and not a lot of dancers will show up at a family gathering, and so forth.

Facial Recognition in LR6 is very poor. Sometimes it does not put the square over the face even in a portrait. In an example folder of 120 photos, the suggested people rectangle was towards the upper left of the photo, unrelated to where the face was, in most photos. Moving the rectangle is a painful task, I have 120,000 photos in my catalog. Sometimes, LR6 guessed correctly even if only part of the face was visible. What then, if I accept, does that mess up all future matches. If I reject, how to I get it to look for the face again. If I move the rectangle, will I live long enough to do all 120,000 photos. Please fix this soon. It is potentially a great tool. Attached is a photo with a face that LR6 could not find.

I'm amazed out how many legs (in jeans no less!) as well as hands, chests, and walls it "detects". Not sure they are quite ready for prime time.

This thread has been running 3 months and there have been LR6 updates but I do not see any improvements in face recognition. Is anybody at Adobe monitoring this discussion and are there any plans to fix it - soon?
